The terms "we," "our," "Artesian," and the "Company" as used herein refer to Artesian Resources and its subsidiaries. The business activity conducted by each of our subsidiaries is discussed below under separate headings.
Our current market area is the Delmarva Peninsula. Our largest service area is in the State of Delaware. Substantial portions of Delaware, particularly outside of northern New Castle County, are not served by a public water or wastewater system and represent potential opportunities for Artesian Water and Artesian Wastewater to obtain new exclusive franchised service areas. We continue to focus resources on developing and serving existing service territories and obtaining new territories throughout Delaware.
We hold Certificates of Public Convenience and Necessity, or CPCNs, for approximately 312 square miles of exclusive water service territory, most of which is in Delaware with some territory being in Maryland and Pennsylvania. Our largest connected regional water system, consisting of approximately 145 square miles and 81,000 metered customers, is located in northern New Castle County and portions of southern New Castle County, Delaware. We hold CPCNs for approximately 61 square miles of wastewater service territory located in Sussex County, Delaware. A significant portion of our exclusive service territory is in Sussex County, Delaware and remains undeveloped, and if and when development occurs and there is population growth in these areas, we anticipate we will increase our customer base by providing water and/or wastewater service to the newly developed areas and new customers.
